论文摘要
与侧向N-I-N和P-I-N连接的石墨烯层（GLS）中的Zener-Klein（ZK）间隧道导致非线性I-V特性，可用于整流和检测Terahertz（THZ）信号。耗尽区域中隧道电子和孔的运输时间延迟导致THZ电流和THZ电压之间的相移，从而导致在一定频率范围内负动态电导，并导致所谓的转运时间（TT）不稳定。 ZK隧道和TT负动力电导的组合使THZ检测以及THZ辐射的扩增和产生。我们根据表现出TT共振（GPIN-TTD）的周期性级联P-I-N结构提出和评估THZ设备。这样的结构可以用作THZ放大器，并将其放置在Fabri-Perot腔中，或耦合到THZ天线或使用环振荡器连接，作为THZ辐射源。
The Zener-Klein (ZK) interband tunneling in graphene layers (GLs) with the lateral n-i-n and p-i-n junctions results in the nonlinear I-V characteristics that can be used for the rectification and detection of the terahertz (THz) signals. The transit time delay of the tunneling electrons and holes in the depletion regions leads to the phase shift between the THz current and THz voltage causing the negative dynamic conductance in a certain frequency range and resulting in the so-called transit-time (TT) instability. The combination of the ZK tunneling and the TT negative dynamic conductance enables resonant THz detection and the amplification and generation of THz radiation. We propose and evaluate the THz devices based on periodic cascade GL p-i-n structures exhibiting the TT resonances (GPIN-TTDs). Such structures can serve as THz amplifiers and, being placed in a Fabri-Perot cavity, or coupled to a THz antenna or using a ring oscillator connection, as THz radiation sources.
